The adoption of plug-in electric vehicles in Australia is driven mostly by state-based electric vehicle targets and monetary incentives to support the adoption and deployment of low- or zero-emission vehicles. The monetary incentives include electric vehicle subsidies, interest-free loans, registration exemptions, stamp duty exemptions, the luxury car tax exemption and discounted parking for both private and commercial purchases. The Clean Energy Finance Corporation, energy providers, car loan providers and car insurance providers also offer their own financial incentives for electric vehicle purchases including Macquarie Bank offering the lowest electric car loan of 2.99%.
